Zusammenfassung:	Embodiments of bladed rotors and methods for manufacturing bladed rotors are provided herein. The method for manufacturing bladed rotors comprises providing a workpiece comprising a first rotor blade segment. The first rotor blade segment comprises a first platform portion on a radially outward end portion of the first rotor blade segment. Further, the method comprises forming a second rotor blade segment, by additive manufacturing, removing a side portion of the first platform portion, and removing a side portion of the second rotor blade segment, whereby a second platform portion remains on a radially outward end portion of the second rotor blade segment.
